Provedor de dados: 32
Autores: Talamantes Castorena, Saulo.
México es centro de origen, domesticación y diversificación del frijol (Phaseolus vulgaris L.) y maíz (Zea mays L.). Ambas especies han sido importantes desde la época prehispánica, y la diversidad fenotípica y genética de ambos cultivos es conservada en forma de poblaciones nativas cultivadas por los agricultores en la actualidad. En la región centro-sur de México, el sistema de producción “milpa” se practica en la actualidad, con base en una gran diversidad de poblaciones nativas de frijol común de crecimiento indeterminado cultivadas en asociación con maíz en el sistema milpa. La diversidad morfológica y genética ha sido estudiada, resultando amplia variación en formas de planta, vaina y semilla. Sin embargo, el potencial de producción, la calidad...

Provedor de dados: 32
Autores: Tun Dzul, José de la Cruz.
El chile poblano en México se cultiva en una superficie de 35,000 ha anuales, pero su   producción es poco rentable debido a su bajo rendimiento (13 Mg ha-1), siendo una de  las principales causas la fertilización inadecuada por desconocimiento de sus  requerimientos nutricionales. La presente investigación estuvo conformada por dos  experimentos y tuvo por objetivo evaluar el efecto del nitrógeno, fósforo y potasio  sobre el rendimiento y la calidad del fruto de chile poblano (cv. Caballero) en  diferentes etapas fenológicas. Los experimentos se realizaron en invernadero y  utilizando hidroponía. En el primer experimento se evaluó el efecto de NO3- (6, 9 y 12  me L-1), H2PO4- (0.5 y 1.0 me L-1) y K+ (5 y 7 me L-1), sobre el crecimiento de las  plántulas,...

Cucumber seedling dependence on cotyledonary leaves for early growth
Provedor de dados: 86
Autores: Bisognin,Dilson Antônio; Velasquez,Luis; Widders,Irvin.
The objective of this work was to evaluate the dependence of cucumber (Cucumis sativus L.) seedlings on cotyledonary leaves for early growth and establishment. Sets of two uniform emerging seedlings were used to quantify the initial growth and dry matter accumulation, as well as the intensity and stage of cotyledon damage in seedling establishment and to determine cotyledon protein, amino acid and carbohydrate contributions to the growing seedling. Cucumber seedling establishment was found to be highly dependent on cotyledonary leaves. Root system establishment was highly dependent on the health of the aerial part. One cotyledon was enough to maintain aerial growth of seedlings after unfolding the first true leaf. Cucumber seedlings depended on both...

Provedor de dados: 86
Autores: OLIVEIRA,CARLOS ALBERTO DA SILVA.
Growth and development variables and dry matter characteristics were studied for cultivar Snowden of potato (Solanum tuberosum L.) to evaluate nitrogen and plant density influence. Disregarding ending of season plant stress, the average number of actives haulms per plant was five and it was not affected by plant spacing. However, seasonal and final number of active haulms per plant were increased at 200 kg/ha of nitrogen. Maximum stem elongation was reached quickly with double density and had the tendency to keep constant at the highest and lowest nitrogen levels after 70 days after planting. Specific stem mass defined as mass per unit stem length was established as an indirect measure of stem thickness and load capacity. Specific leaf mass position in...

ABSTRACT: Horseweed control through application of 2.4-D in the winter season is an alternative to manage biotypes resistant to herbicides that belong to other mechanisms of action. The objectives of this study were to assess the physiological quality of wheat seeds and determine the rate of 2.4-D residue, as function of application stages and herbicide rates. The treatments were arranged in factorial scheme, with three application stages (flowering, soft dough and hard dough), and four 2.4-D rates (0; 504; 1,008 and 2,015 g a.i. ha-1). The application of 2.4-D in the wheat crop changed physiological seed quality by increased the rate and total percentage of germination. The application of 2.4-D resulted in herbicide accumulation in seeds, especially when...

The effects of 0, 30 and 60 mM NaCl and substrates (red peat, sand or 3:1:1 [w/w] mixture of peat, sand, or soil) on vegetative growth of lulo, an Andean fruit species, during 12 weeks were studied. The experiment was carried out by using 2000 cm³ of polypropylene plastic pots under greenhouse conditions. Plant height, number of leaves and nodes, leaf area, total plant dry matter (DM), and shoot/root ratio were evaluated. With the increase of salt concentration, the plant height, the number of leaves and nodes, the leaf areas and plant dry mass DM decreased, whereas shoot/root ratio increased. Sand grown lulo plants were most affected by salinity and presented total mortality at 60 mM NaCl. On the other hand, plants held either in peat or in substrate...

ABSTRACT We aimed to evaluate the effects of glyphosate as a chemical desiccant on the nutritional quality, fermentation pattern, and aerobic stability of wilted black oat (Avena strigosa Schreb) silage. Black oat sowing occurred in the first fortnight of May 2013. Desiccant application took place when oat reached milky/dough grain stage (96 days after planting). Glyphosate dosages evaluated were 0, 500, 750, 1000, and 1250 mL ha−1. Three days after desiccation, all treatments were ensiled, and the silos were kept stored for 150 days. A completely randomized design was used, and all statistical procedures were performed by means of Bayesian Inference. Treating herbage prior to ensiling from 500 mL ha−1 glyphosate increased dry matter and organic matter...

Salinity reduces carbon assimilation and the harvest index of cassava plants (Manihot esculenta Crantz)
Provedor de dados: 1
Autores: Cruz, Jailson Lopes; Coelho Filho, Mauricio Antonio; Coelho, Eugenio Ferreira; Santos, Andrade Alves dos.
 This study was developed to evaluate the effects of salinity on the growth and gas exchange of cassava plants, cultivar Verdinha. The four concentrations of NaCl (mM) were as follows: 0, 20, 40, and 60. Under salinity, the lowest concentration of Na+ ions was observed in the tuberous roots; however, the dry matter of tuberous roots was reduced with an application of just 20 mM NaCl. The harvest index was reduced 50% with the highest salt concentration. Salinity reduced carbon assimilation (A), stomatal conductance (gs), transpiration, and the instantaneous water use efficiency. The correlation between gs and A was high and positive, showing that stomatal movement was one of the responsible for the lower A. Under salt stress, there was an increase in...

Provedor de dados: 115
Autores: Cavalcante,Valeria Santos; Prado,Renato de Mello; Vasconcelos,Ricardo de Lima; Campos,Cid N. Silva.
Abstract Doubts remain about the adequate iron (Fe) concentration in nutrient solutions used for optimal plant growth, especially in gramineae like sugar cane (Saccharum officinarum L.). Therefore, the aim of this study was to evaluate the effect of Fe concentrations on growth, green color index and dry matter (DM) production in sugar cane cultivated in a nutrient solution. The hypothesis was that the nutrient solution must contain higher Fe concentration, which is used by the plant for optimum development.

A model describing the relationship between electrical conductivity and forage dry matter content
Provedor de dados: 52
Autores: Ashbell,Gilad; Evers,Evert; Bosma,Ate H.
The correlation between dry matter (DM) content, electrical conductivity (EC) and ash content was found to be linear in grass and alfalfa during drying. While minerals in grass and alfalfa were very stable components during drying, their concentrations and EC increase accordingly; therefore, the EC value could serve as a measurement to determine DM content. Results indicated that EC measurement in grass and alfalfa during drying was simple, accurate, fast and easily repeatable, and could serve as an alternative method for DM determination.

Autores: Scavroni,Joseane; Ferreira,Leonardo Cesar; Valmorbida,Janice; Boaro,Carmen Sílvia Fernandes.
Development of Mentha piperita L . on biosolids amended soil with levels equivalent to 0, 28, 56 and 112 t ha-1 was evaluated. In order to measure the productivity and its relation with mint essential oil yield, different indices were determined: leaf area, total and several organ dry matter, leaf area ratio, specific leaf area, net assimilation rate and relative growth rate at 30, 44, 58, 72 and 86 days after planting (DAP), and essential oil yield at 90, 110 and 120 DAP. Physiological indices revealed that biosolids prolonged the vegetative phase of the plants, which adapted themselves to the presence of biosolids with time. Plants showed inverse behaviors in relation to productivity, resulting from the primary metabolism, represented by the shoot dry...

Ruminal degradation of dry matter (DMD) and crude protein (CPD) for aerial biomass at the flowering stage and for the seeds of L. campestris, L. exaltatus, L. hintonii and L. montanus was determined using the nylon bag technique with two fistulated steers in five incubation times (3, 9, 12, 24 and 48 h), including a sample of soybean paste (SP). The data obtained were analyzed using PROC MIXED of SAS for repeated measures. The results showed interactions between species and incubation time for DMD and CPD. Among species of lupine, a high DMD and CPD of seeds were observed after three hours of incubation. At 48 h, DMD and CPD did not show significant variation between species: DMD ranged from 94.3% to 96.7% and CPD from 98.9 to 99.2%. The degradation rate...

For confined animals, performance is improved when their diet is supplemented with a mineral mixture and protein energy. This study evaluated the effect of dietary supplementation on feedlot sheep on native pasture. Two experiments were conducted in sequence, with the animals constrained in one and animals confined to pasture in the other. The experiments were conducted with 32 Santa Ines lambs, with average initial weights of 16.8 and 19.9 kg for the constrained and pasture studies, respectively. In both experiments, the animals were offered the following supplements: Supplement 1 = 200 g of the concentrate without mineral mixture; Supplement 2 = 200 g of the concentrate with mineral mixture + Mn + Zn; Supplement 3 = 300 g of the concentrate with mineral...

ABSTRACT:  Plant growth analyses are important because they generate information on the demand and necessary care for each development stage of a plant. Nonlinear regression models are appropriate for the description of curves of growth, since they include parameters with practical biological interpretation. However, these models present information in terms of the conditional mean, and they are subject to problems in the adjustment caused by possible outliers or asymmetry in the distribution of the data. Quantile regression can solve these problems, and it allows the estimation of different quantiles, generating more complete and robust results. The objective of this research was to adjust a nonlinear quantile regression model for the study of dry matter...

ABSTRACT: This study aimed to evaluate the effects of replacing oat hay with coffee husk in the diet of lambs on the intake and apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), non-fiber carbohydrate (NFC), neutral detergent fiber (NDF), and acid detergent fiber (ADF). The experimental design was 4×4 Latin square with four levels of replacement of oat hay with coffee husk (0, 7.5, 15, and 22.5%) with four individually housed Texel sheep. Intake and apparent digestibility coefficients were measured at four periods of 12 days. All orts and feces were collected, weighed, homogenized, and sampled. The use of coffee husk at up to 22.5% of the total DM in the diet of lambs improved the intake of nutrients....

Due to the seasonal cycle of forage, the use of silage to feed animals provides nutrients throughout the year. However, its quality can be improved with the inclusion of additives and other products. Glycerol is a rich source of energy and present a high efficiency of utilization by animals. The purpose of this work was to evaluate the effect of glycerol inclusion on the chemical and fermentation characteristics of corn and sunflower silages. Two silage sources (maize and sunflower) were used and four levels of glycerol inclusion (0, 15, 30 and 45%) based on dry matter were carried out. The experimental design was completely randomized in a 2 x 4 factorial arrangement with five replications. The pH values and chemical composition of corn and sunflower...
